Windows Phone 7 Page Transitions very slow using Toolkit

I have the problem that whenever I use the Page Transitions from Windows Phone 7 Toolkit, the transitions are very slow and the whole app seems to have framed drops. The animations are "stuttering".

Is anyone else experiencing this? I'm using the TransitionFrame class as RootFrame and in the .xaml pages I'm using code like

<toolkit:TransitionService.NavigationInTransition>
        <toolkit:NavigationInTransition>
            <toolkit:NavigationInTransition.Backward>
                <toolkit:TurnstileTransition Mode="BackwardIn"/>
            </toolkit:NavigationInTransition.Backward>
            <toolkit:NavigationInTransition.Forward>
                <toolkit:SlideTransition Mode="SlideDownFadeOut" />
            </toolkit:NavigationInTransition.Forward>
        </toolkit:NavigationInTransition>
    </toolkit:TransitionService.NavigationInTransition>
Solution

  • I'd recommend against using the WP7 Toolkit Page Transition animations.

    If you activate the performance counters you can see that just by changing the root frame to the WP7 frame, your fill rate is increased by 1. Since fill rates even in the best of apps are 1.5+ and the recommended maximum is 2.5, I'd say that's very bad.

    Telerik has a WP7 Page transition control you might want to checkout. But honestly, I couldn't find/code any generic page transition that gives a well-performing page flip effect.
